  • When mocking a class with Moq, how can I CallBase for just specific methods?

    - by Daryn
    I really appreciate Moq's Loose mocking behaviour that returns default values when no expectations are set. It's convenient and saves me code, and it also acts as a safety measure: dependencies won't get unintentionally called during the unit test (as long as they are virtual). However, I'm confused about how to keep these benefits when the method under test happens to be virtual. In this case I do want to call the real code for that one method, while still having the rest of the class loosely mocked. All I have found in my searching is that I could set mock.CallBase = true to ensure that the method gets called. However, that affects the whole class. I don't want to do that because it puts me in a dilemma about all the other properties and methods in the class that hide call dependencies: if CallBase is true then I have to either Setup stubs for all of the properties and methods that hide dependencies -- Even though my test doesn't think it needs to care about those dependencies, or Hope that I don't forget to Setup any stubs (and that no new dependencies get added to the code in the future) -- Risk unit tests hitting a real dependency. Q: With Moq, is there any way to test a virtual method, when I mocked the class to stub just a few dependencies? I.e. Without resorting to CallBase=true and having to stub all of the dependencies? Example code to illustrate (uses MSTest, InternalsVisibleTo DynamicProxyGenAssembly2) In the following example, TestNonVirtualMethod passes, but TestVirtualMethod fails - returns null. public class Foo { public string NonVirtualMethod() { return GetDependencyA(); } public virtual string VirtualMethod() { return GetDependencyA();} internal virtual string GetDependencyA() { return "! Hit REAL Dependency A !"; } // [... Possibly many other dependencies ...] internal virtual string GetDependencyN() { return "! Hit REAL Dependency N !"; } } [TestClass] public class UnitTest1 { [TestMethod] public void TestNonVirtualMethod() { var mockFoo = new Mock<Foo>(); mockFoo.Setup(m => m.GetDependencyA()).Returns(expectedResultString); string result = mockFoo.Object.NonVirtualMethod(); Assert.AreEqual(expectedResultString, result); } [TestMethod] public void TestVirtualMethod() // Fails { var mockFoo = new Mock<Foo>(); mockFoo.Setup(m => m.GetDependencyA()).Returns(expectedResultString); // (I don't want to setup GetDependencyB ... GetDependencyN here) string result = mockFoo.Object.VirtualMethod(); Assert.AreEqual(expectedResultString, result); } string expectedResultString = "Hit mock dependency A - OK"; }

  • Collision Detection for arbitrarily sized, positioned and rotated rectangles in XNA

    - by Stefan
    I'm working with xna in C# and in my game I will have a variety of space ships flying all over the place. They will each have an arbitrary rotation, size and position in space and I need a method to determine when they collide. Ideally the method would take two Rectangles, two doubles and two Vector2s for size, rotation and position respectively and return a boolean that indicates whether they have intersected or not.

  • What is the different purpose of .H header file and a IDL file?

    - by smwikipedia
    I am studying COM so there're some basic questions puzzling me... I know that IDL file is used to describe the method definitions (or the so called 'contract' between software modules), and the .H header files contains something like a method prototype, which looks similar to what the IDL is meant for. So, why are these two things coexist? Isn't one enough? Many thanks.

  • help for splitting a string in javascript

    - by Hero
    Hi everyone... I'd asked a question about the splitting the a string like below: Input string: "a=aa| b=b||b | c=cc" and the output: a=aa b=b||b c=cc Kobi's answer was: var matches = "a=aa|b=b||b|c=cc".match(/(?:[^|]|\|\|)+/g) his answer was correct. But I need to use "split" method and save store the outputs in a array. so I can't use the Match Method. So please help me...

  • Override generic methods in c#

    - by Pascal
    I thought I can not override generic methods of a derived class. http://my.safaribooksonline.com/book/programming/csharp/9780071741163/generics/ch18lev1sec13 The code in this link runs fine. The overriden method is called although the instance type of the base class is used and not the instance of the derived type. Now I am confused because a former question of mine Type parameter declaration must be identifier not a type is about calling the overriding generic method with the instance of base type which did NOT work!

  • getJSON triggered from a button inside a form

    - by nav
    Hi, I'm having trouble understanding why I have to place the button triggering the getJSON method outside of the form for the request to work. If the button is placed within the form then the getJSON method returns no results. The code bascially makes a XHR request on clicking the Submit button, based on the value selected. I have replicated the issue here: http://jsfiddle.net/z6caj/ Many Thanks,

  • Building a balanced binary search tree

    - by Znarkus
    Hi! Is there a method to build a balanced binary search tree? Example: 1 2 3 4 5 6 7 8 9 5 / \ 3 etc / \ 2 4 / 1 I'm thinking there is a method to do this, without using the more complex self-balancing trees. Otherwise I can do it on my own, but someone probably have done this already :)

  • How to modify raw HTML of ASP.NET page on PreRender?

    - by ace
    I want to access the raw HTML code that my ASP.NET System.Web.UI.Page is about to render. How can i do that? Is there a property or method like System.Web.UI.Page.HTML or something like that. I know I could loop through the Controls List of the page and get access to all the Literal Controls etc, but I was wondering if there's a direct property or method that can return me the raw html, which I can modify just before rendering the page.

  • How would I rspec/test an updated_at field without using sleep() in ruby?

    - by Kamilski81
    How do i write my spec without using the sleep(1.second) method? When I remove the sleep then my tests break because they are returning the same time stamp? I have the following class method: def skip qs = find_or_create_by(user_id: user_id) qs.set_updated_at qs.n_skip += 1 qs.save! end and following spec: qs = skip(user.id) sleep(1.second) qs2 = skip(user.id) qs.should_not be_nil qs2.should_not be_nil (qs.updated_at < qs2.updated_at).should be_true

  • How to define a constant when running script/server?

    - by Zeke
    I want to start up my Rails development server like this: script/server OFFLINE_MODE=1 and have a method that checks for the presence of that constant: helper_method :offline_mode? def offline_mode? defined?(OFFLINE_MODE) ? true : false end so I can hide stuff in my app when I'm coding without access to the internet. For some reason though, OFFLINE_MODE doesn't ever seem to be defined and the method always returns false.. thoughts?

  • Dynamic swappable Data Access Layer

    - by Andy
    I'm writing a data driven WPF client. The client will typically pull data from a WCF service, which queries a SQL db, but I'd like the option to pull the data directly from SQL or other arbitrary data sources. I've come up with this design and would like to hear your opinion on whether it is the best design. First, we have some data object we'd like to extract from SQL. // The Data Object with a single property public class Customer { private string m_Name = string.Empty; public string Name { get { return m_Name; } set { m_Name = value;} } } Then I plan on using an interface which all data access layers should implement. Suppose one could also use an abstract class. Thoughts? // The interface with a single method interface ICustomerFacade { List<Customer> GetAll(); } One can create a SQL implementation. // Sql Implementation public class SqlCustomrFacade : ICustomerFacade { public List<Customer> GetAll() { // Query SQL db and return something useful // ... return new List<Customer>(); } } We can also create a WCF implementation. The problem with WCF is is that it doesn't use the same data object. It creates its own local version, so we would have to copy the details over somehow. I suppose one could use reflection to copy the values of similar fields across. Thoughts? // Wcf Implementation public class WcfCustomrFacade : ICustomerFacade { public List<Customer> GetAll() { // Get date from the Wcf Service (not defined here) List<WcfService.Customer> wcfCustomers = wcfService.GetAllCustomers(); // The list we're going to return List<Customer> customers = new List<Customer>(); // This is horrible foreach(WcfService.Customer wcfCustomer in wcfCustomers) { Customer customer = new Customer(); customer.Name = wcfCustomer.Name; customers.Add(customer); } return customers; } } I also plan on using a factory to decide which facade to use. // Factory pattern public class FacadeFactory() { public static ICustomerFacade CreateCustomerFacade() { // Determine the facade to use if (ConfigurationManager.AppSettings["DAL"] == "Sql") return new SqlCustomrFacade(); else return new WcfCustomrFacade(); } } This is how the DAL would typically be used. // Test application public class MyApp { public static void Main() { ICustomerFacade cf = FacadeFactory.CreateCustomerFacade(); cf.GetAll(); } } I appreciate your thoughts and time.

The method declaration would look something like this: long getRevisionNumber(String localPath) { ... } I'm trying to use SVNKit for this, but it seems to require an SVN URL to start with. Is there any way to start with a local path?

  • upgrading boost version

    - by idimba
    I'm using RHEL 5.3, shipped with gcc 4.1.2 and boost 1.33. So, there's no boost::unorded_map, no make_shared() factory function to create boost::shared_ptr and other features available in newer releases of boost. Is there're a newer version of boost compatible with the version of gcc? If yes, how the upgrade is performed?
